20 Brothers, stop thinking like children. In regard to evil be infants, but in your thinking be adults. 21 In the Law it is written:
"Through men of strange tongues and through the lips of foreigners I will speak to this people, but even then they will not listen to me," says the Lord.
22 Tongues, then, are a sign, not for believers but for unbelievers; prophecy, however, is for believers, not for unbelievers.
